By ELIZA A. BO\VEN. 



4to. 90 pages. 



An elementary text-book for High-Schools and Academies, based on 

 the most practical and interesting method of studying the subject — that 

 of observation. To assist the pupil in his work, careful directions are 

 given when, how, and where to find the heavenly bodies ; also for observ- 

 ing, in entertaining and instructive ways, the characteristics and phenom- 

 ena of the constellations. Their motions are described in familiar 

 language, in the order in which they can be seen by an observer. The 

 large quarto pages admit maps and views on a scale that will give a 

 clear conception of the vast expanse of the celestial regions.
